residing at Cani Luis Obispo and have invented a new and useful Vehicle-Spring, of which the following is a specification. l

IThis application is designed to cover features of invention divided out of our appliled Novenibei' 30., 1910, and certain improvements thereof. An object of the invention is to provide a superior spring aii'ording gently yielding resilient support for heavy and light `loads alike;` the resistance of the spring inc-reas bria, in the county of San ing and decreasing as the burden oi the load increases and decreases.

A. further object is to provide a vehicle spring in which the amplitude of movement is limited by resilient means. to inake adjustabl'e the yliinits of unrestricted inofeinent, and to provide ineaiis whereby the resistancef oeredby the sprin@V at the close of `stay for the. usual parts oli' such. spring,

its `distortion vand recoil or or either, may be regulated.y Y. 1 Another obiect is to reduce the `liability oi silient element that at all tiin'es serves as a i Y and to provide ineans to obstruct such stay and pply its resilient force niore oi' less forciblivas desired under different workin@ requireinents and conditions. Y

TheA invention l,is applicable to various forms ofvehicles, but is more -particulary applicable as a shock absorber for antonio* the invention.

is a view in which a three-fourths elliptic spring is employed and in which lthe chassis and the upper quarter elliptic spring constitute the equivalent of the upper half elliptic spring-shown in Fig. l. Fig. 5 is a plan of the device shown in F ig. 4. Fig-6 is a view orf another embodiment of the iii-.-

vention. Fig. 7 is a fragniental plan detail oiI parts shownin Fig.'6. Fig. S is a perspective view of `the duplex buniper detached.

ln the drawings like characters designate similar parts; indices being added to some of suoli characters to avoid confusion with `reference to parts' that are not wholly similar.

In F ig.l there is shown the combination with a half-elliptic spring l, of a lever spring 2 ulcruined to one end 3 of the halfelliptic spring and having a short arni d and a longl arin :3: the long arin being resilient: a shackle 6 connectingthe end oic the long aiin with the other end 7 oi` the half-elliptic spring: a supported body in the forni of a second' half-elliptic spring 8 connected at one end 4with the same end T of the half-elliptic spring 'l as the lever aiin 5 and a shackle 1.0 connecting the short arm il. of the lever spring with the' other end 1l of the second half-elliptic spring 8.

l2 represents asiipporting bod;v as an axle of the vehicle which is resiliently connected through the half-elliptic spring l and lever spring 2 and their' shackles with -a supported body which niay in soine instances be resilient and in` other instances be non-re silient.

In Fig. l the second half-elliptic spring 8 constitutes the resilient supported body, andit in turn supports the ciassis body 8. In Fig. 2 the supportedbody 8 is the chassis body of the vehicle.

In Fig. 'l the end l1 of the upper halfelliptic spring 8. is bent downwardly underneath the end of the arm 4 so that the shackle 10 niay swing beneath such arm.'

ln Fig. 2 the shackle l0 isswun'g from a supported body in the forni of a chassis S and is pivotally connected With the. shorl arm 4 of the lever sprinv.

All ofthe pivotal connections shown in either of the views are made by pins and roller bearings'l and the long resilient arm 5 is sufficiently limber to Contact with the supported body or a bumper 14. In some cases no bumper is provided and conse- "'quently'the limber arm b under heavyiloads way in such cases come into contact directly with the chassis body 8".

Thev shackle l6 may be connectedV with the end '7' of the halfeelliptic'spring;1, at a' va riable distance from the tip 1 6 of, saidspring end'7 that is connected t'o the chassis 8 or tothe end 9, of the upper half elliptic spring.

The shacklesmay be of any desired con- 'struction and are 'shown as pairs of rigid 'swinging links pivotally connected at'their ends with the parts to be `connected.
